How are pigmented lesions treated?

Pigmented lesions are treated using the Varilite diode laser by Iridex or with cryotherapy, whichever approach is best suited to the specific lesions.  Both methods are highly effective.

What can I expect during the treatment?

LASER:  The laser treatment is a hot sensation because light converts to heat energy as it enters the skin. Cool packs can be used beforehand to minimise discomfort.  Directly after the treatment the skin may tingle a bit but there is no lasting discomfort.  Normal routine can be resumed directly so a lunchtime session is possible.

CRYOTHERAPY: This is a freeze technique and the sensation is bearably cold and lasts only seconds. There is no pain afterwards, only a slight itch as histamine is released.




Is there any down time?  

LASER:  Over a few days after the treatment the pigmented lesions darken as the melanin in the skin (the pigment) accumulates on the surface as a microcrust. Concealer can be used if necessary as it becomes a darker version of the untreated lesion.

CRYOTHERAPY: After cryotherapy the skin may blister and this is indiscriminate but easily managed.  It doesn't always happen. Whether it blisters or not, the treated area dries out and the pigmentation becomes dark and crusty before dropping off after two or so of weeks.

How long will it take to see the results?

After ten or so days following the treatment the microcrusts of pigment slough off leaving a clear or lighter area beneath.  

When the pigment comes off the new skin may be slightly pink but will even out again over the coming weeks. While the skin is healing care must be taken not to expose the area to bright sunlight.

How many treatments are needed?

One or two sessions may be required.

How much does it cost?

The cost of this treatment depends on the number of lesions and the size of the area treated.  During a free consultation we will assess the best method of treatment and agree the cost, starting from £50.
